a cotton cleaner which will handle any hind.

of staple or lint cotton of all grades, as Well as seed cotton, bells, Waste lint from gins and damaged lcot-ten. A further object ofthe invention is to provide a cleaner Which Will clean any lrind of cotton and separate the fibers at the same time so as to discharge it free from foreign mattei', mats and in the best condition. f

Another object `is to provide a vcotton cleaner which removes the kdust-and at the same timev opens up and disintegrates the charge of cotton which is introduced into the cleaner. This ypermits the airxto pass freely thru the cotton, and offers a superior means of cleaning and disintegrating, particularly cottonof a low staple and particularly bats which are very dirty.

- A construction designed tocarry out the invention Will be` hereinafter described together With other `features of the invention. The invention Will be more readily understood from a reading of the following specification and by reference to the accompanying drawings, in which an example of the invention is shown and wherein-z Fig. 1 is a side'elevation of a cleaner f constructed in accordance With my inven- V tion, a portion being brclren away to illustrate the cleaning chamber, i

Fig. 2 is aV transverse vertical sectional view on the lines 2-2 of Fig. 1,

Fig. 3 is a perspective in detail showing the manner of fastening the cleaner blades on the shaft,

Fig. 4.- is a plan vien7 with the cover seiction 0f the chamber removed, and

Fig. 5 is an underside view.

In the drawings the numeral -10 designates a base frame on which end standards 11 are suitably mounted. The end standards 11, support .vertical end Walls V12 Which are connected with side Walls 13,'said Walls ...preferably being formed of ysheet metal and suitably secured to the standards. The side and end Walls form a housing which has COTTON GLEANR.

Serial No. l$1,600.

a laterally directed flange 1l along its upper side which receives the side flanges 15 of a semi-cylindrical cover or hood 16, which is closed at its end and registers with the end Walls 12.

At one end the cover is provided with a feed hopper 17 opening into the cleaner chamber Within said cover. This hopper is placed at one side just above the flange 15. The cleaner chamber has a concaved bottom disposed Within the housing, one half of which bottom is formed of foraminous material such as Wire netting 18, While the other half 19 is preferably formed of sheet metal and is imperforated except for a discharge opening 2O at the end opposite to the hopper 17. The chamber is cylindrical in shape and a longitudinal beater shaft 2l extends therethru, said shaft being suitably supported in bearing boxes at the upper end of the standards 11. A pulley 22 is mounted on one end of the `shaft and a similar pulley 23 is mounted on the other end of the shaft. Fast and loose pulleys 2l and 25` are also mounted on the shaft for driving the same. A plurality of beater blades 26 are mounted on the shaft and disposed radially.` These blades are positioned so` that their outer ends are co-ordinated in the form of a helix as is clearly shown yin Fig. 1. Thus When the beater is revolved this arrangement causes the cottonA to be conveyed from the hopper end to the opposite end of the cleaner charnber.

The manner of fastening the beater blades on the shaft 21 is simple and effective. but may be changed Without departing from the spirit of the invention. 'Each `blade is twisted upon itself so as to provide a shank 2,7 at right angles tothe rest of the blade. This shank is rolled at its inner end te form an eye 28 thru which the shank of a hooi: bolt 29 is passed and held `by a nut 30. The hook of the bolt 29 is engaged over the shank of the opposite beater blade which is (lisposed upon the other side of the shaft. By directing` the blades in the opposite directions and disposing their hoot: bolts on opposite sides of the shaft as is shown in Fig. 6, the blades will be securely held in position. By loosening the nut 30 any blade may be reinovedand replaced or repaired. rlhe ends of the blades revolve in proximity to' the cover 16 and the concaved bottom of the chamber. Studs 81 projert cleaning chamberand freely discharge down and arevdisposed so that the blades pass therebetween. Similar studs 32 are mounted in the side Walls immediately beloM7 the flanges 14 and also project .between vthe blades. These Studs are preferably screw threaded and are provided Witlrlocknuts for holding them in position.

Under the screen 18 a trough :Se is 'disposed longitudinally of the housing, While asimilar trough 35 is disposed under the `bottom 19. These troughs have their inner sides meeting along the center of thehousing and contacting atthe intersection of the parts18 and 19. By this arrangement all Ydust and dirt which is separated from Vthe'cotton passesthru, the screen 18 into the trough 3ft, -While the cotton is vconveyed to the end of the chamber and discharged thru the opening 2O into thetrough At the end of the trough 34C a suction fan V86 vis arranged and draws-the dirt andforeign mat vter from the trough 34 and discharges it thru a spout 3'? in the side of the housing. At the opposite end of th'etrough B5 a suction fan 38 is arranged-and is`prov`*ided on its upper side with a discharge spout 39 extending thru the side Wall 12,. The Vend lWall 12 is provided `with an opening 40 which admits-air to the trough 35 at the end opposite to the fan 38, said opening Ll()` be ingbelo'w the opening 20. This opening 4l() `adlnits air so that the cotton may be easily conveyed along `thebottom of said-trough.`

Thefan 36 is provided v-with a pulley 4-1 which is driven byV means of a belt 42 lfrom the pulley 23; While the fan 38 is provided with a pulley 43, driven by a belt lll-from the pulley 22. By this arrangement motion is transmitted tothe beater shaft 21 `which in turn operates both of the fans. it will benoticed that thelfans are disposed at opposite ends of the machine and this arrangement gives the cotton time to pass thru the fed in a suitable manner thru the -hopper 17 and is -immediately attacked by the revolving beater blades 26, which carriesjthcv cotton aroundthe chamber and drags the fibers between the studs Sland 32. -This causes Vthe cotton and etc., tobe` quickly broken up and disintegrated sothattheair which is dravvnin thru the `hopper'17 l byy the fan 36 vhnmediately removes the dust. VThe helical arrangement ofthe blades causes the cotton to travel vtoward the opposite end ofthe1 cleaningchamber. By quickly disintegrating the cotton thedust is freed to- Agetlrer With other foreign matter and is drawn down thru the screen 18. This is very important .because the beater being rapidly revolved breaks up the charge in a very eiiicient manner .and carries out a thorough cleaning operation;

4Repeated tests have shown that when the cotton reaches the opening 2O itis thoroughly cleaned and is discharged down thru said opening in this state into thetrough 35. The fan 38 carries theV cotton out ofthe ltrough and discharges itvthru the spout 39.
